IMPROVEMENT IN TRUNK-LOCKS.

Specification forming part of Letters Patent No. 201,480, dated March19, 1878 application filed January 25, 1878.

, marked thereon, which form a part of this specification.

My invention is a trunk lock or catch consisting of a case containing abolt turning on a pivot attached to the case, having lugs arranged to bestruck by the key, and with beveled faces adapted to a spring-plate, asfully described hereinafter.

In the drawing, A represents the look, the view being taken from theback of the lock on the side designed to fit against the surface of thetrunk. B is the hasp, provided with holes m for nails or rivets, andconstructed at the tongue, which fits into the lock, With a hook, I),strengthened in its attachment to the hasp by a plate, 6, the same beingplaced at one side of the hook, to leave an opening (in which the plate0 is placed) for the hooked bolt a. This bolt is cast in one piece, witha plate notched at its other extremity, and pivoted about the middle atd.

The key of the lock h is inserted through a key-hole, and, in beingturned, enters the notch between two lugs, i '6, formed at the cornersof the plate named, and pushes against the lug t to unlock the bolt, andagainst t" to lock it.

To retain the bolt firmly in either position, the plate a i i is cast atthe back side. with a projecting hub flattened on two sides, as shown atg. A spring-leaf, f, extends across the interior of the case, resting atits ends on seats 12, and bearing at its middle against the flattenedhub of the bolt-plate a c i. The bolt is thus firmly held either in theopen or closed position.

The plate named may be made, as shown, with a tapering hole in itsmiddle for facility of casting, in which case it fits on a tapered pincast in the center of the lock; or it may be made with a projecting pinon its front or back, resting in holes or recesses provided in the frontand back of the lock.

As shown in the drawing, the lock requires no back plate to aid insupporting the mechanism.

I claim- The combination, with the case A, of the bolt a, turning on apivot attached to the case, having lugs '6 v1, arranged to be struck bythe key, and with beveledfaces adapted to aspringplate, as set forth.

In testimony that I claim the foregoing as my own I hereto affiX mysignature in presence of two witnesses.

JoEN ARNOLD.
